Title (EN) COMBINED ROD-DISC CRYSTALLINE SYSTEMS WITH NEMATIC PROPERTIES
(FR) SYSTEMES COMBINES TIGES-DISQUES PRESENTANT DES PROPRIETES NEMATIQUES ORIGINALES
Abstract:
(EN) A liquid crystal compound comprising a discotic nematic phase promoting moiety, comprises a disc shaped mesogen, and at least two calamitic nematic phase moieties, comprising rod shaped mesogens.
(FR) L'invention a trait à un cristal liquide caractérisé en ce que son groupe fonctionnel favorisant la phase nématique discotique contient un groupe fonctionnel en forme de disque. L'invention concerne également un composé représenté par la formule (I), qui renferme un mésogène en forme de disque et un mésogène en forme de tige.
